Abstract: PURPOSE:To simplify an azimuth detector by finding the zero-crossing point of the 2nd higher harmonic obtained by adding the outputs generated when flux gate sensors arranged orthogonally are respectively driven by flux gate driving electric power sources shifted by 45 deg. to each other. CONSTITUTION:The output of a clock generator 11 is counted up by a counter 12 and, flux gate driving electric power sources ebx 64 , eby having 45 deg. phase shift to each other are outputted from power amplifiers 18, 19 through a T type flip-flop (FF) 14, a D type FF, and inverters 16, 17. Flux gate sensors 20, 21 are arranged orthogonally to each other detect (x) and (y) components of the magnetic field ex, ey and driven by the flux gate driving electric power sources ebx, eby. The output of sensors 20, 21 are proportional to the (x) and (y) components of the magnetic  field and are generated as signals which have the frequency equal to twice the driving frequency and have 90 deg. phase shift to each other. These ouputs are added by  an adder 22 and a signal exy is obtained through a band pass amplifier 23. By latching the count value from the leading edge of ebx to the zero-crossing point of eby,  the detected azimuth is dis played digitally.

Title: Control circuit of machinery
Inventor: NAKAMURA MASAKI
IPC: G05F5/00
Filed: 1980-10-29
Abstract: PURPOSE:To ensure the optional setting for the change of time limit to the fluctuation factor of power supply voltage, by amplifying the fluctuation of the power supply voltage through a simple constitution. CONSTITUTION:When a power supply switch 2 is closed, the reference voltage set at a constant level is applied to the gate terminal of a PUT12. At the same time, a TR17 and a thyristor 16 are turned on and off respectively. Accordingly no current flows to a solenoid 15, and the switch 2 is kept closed with conduction to a heater 14. When the charging voltage of a capacitor 6 reaches the reference level, the PUT12 is turned on with the TR17 turned off. The current flowing to a constant voltage diode 9 flows into the gate of the thyristor 16 to turn on the thyristor 16. Then the current flows to the solenoid 15, and the switch 2 opens to discontinue the conduction to the heater 14. With the fluctuation of the power supply, the charging voltage to be applied to a CR integral network 3 becomes equal to the voltage obtained by dividing the voltage obtained by under-cutting the constant voltage VZ by resistances 19 and 20 and by the function of a constant voltage diode 18.

Title: Copying machine
Inventor: IWAO SOICHI
IPC: G03G21/00
Filed: 1987-06-19
Abstract: PURPOSE:To enhance operability by providing a print key for starting a copying operation and a print key for setting copying conditions. CONSTITUTION:A CPU 70 sets the copying conditions through an operating key. When the conditions are in a standard status, a control signal is outputted to controllers 73-79 through either of a 1st printing key 61A and a 2nd printing key 61B in order to activate the copying operation. When specific copying conditions are on a specified copying condition other than the standard condition, e.g. when the magnification is not unmagnification and in case of copying attending with edition, the key 61A alone cannot activate the operation. In that case the control signal is outputted only when the key 61B is operated after the conditions have been reset to the standard. When no copy is carried out in a prescribed time after the specific conditions have been set or after copying has been carried out once under said conditions, they are reset to the standard automatically. Thus a useless copy without being noticed by special copying condition is eliminated and economy and operability can be improved.

Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent closure of a bypass passage in a throttle valve in which an idle intake regulation valve of an internal combustion engine is provided by a combustion product. SOLUTION: In an idle intake control device, an outlet passage 8 in the downstream of an idle intake regulation valve 3 provided in a bypass passage 12 of a throttle valve 11 is bent, and an accumulation chamber 9a is provided under an accumulation chamber passage 9 extended from the outlet passage 8 on the opposite side of an outlet opening 8a. When a combustion product 6 in an intake chamber 5 flows on an reverse flow 7 to invade into the outlet passage 8, it goes straight to advance to the accumulation chamber passage 9 to be stored in the accumulation chamber 9a, so it will not invade into an idle intake regulation valve 3.  As a ball body 17 of metal is contained in the accumulation chamber 9a, it rolls in the accumulation chamber 9a by vibration of an engine to crush the combustion product 6, so fine grain of the combustion product 6 flows on a normal flow 4 of idle intake to be sucked to return to the intake chamber 5. The accumulation chamber 9a may be composed replaceable.
